SPECIFICATION C254 - SEGMENTAL PAVING GENERAL

C254.01 SCOPE

1. This Specification covers the construction of both clay and concrete segmental paving for road pavements, medians, traffic islands, driveways, cycleways, footpaths and other pedestrian areas.

2. The work to be executed under this Specification consists of the supply, placement and compaction of segmental pavers including the provision of a sand bedding course and joint filling sand, over bound or unbound base and/or subbase layer/s.

3. This Specification should be read in conjunction with the appropriate Specifications for the construction of the base and subbase layers beneath the segmental paving, ie. FLEXIBLE PAVEMENTS, MASS CONCRETE SUBBASE.

4. Requirements for quality control and testing, including maximum lot sizes and

minimum test frequencies, are cited in the Specification Part for Quality Requirements. Quality

C254.02 TERMINOLOGY

1. Concrete segmental pavers are units of not more than 0.10 square metres in gross plan area, manufactured from concrete, with plain or dentated sides, with top and bottom faces parallel and with or without chamfered edges.

Size

2. Concrete pavers are identified by shape as being one of the following types, examples of some common shape being included in Figure C254.1 below:

Shape Type A

Dentated chamfered units which key into each other on four sides, are capable of being laid in herringbone bond, and by their plan geometry, when interlocked, resist the spread of joints parallel to both the longitudinal and transverse axes of the units.

Concrete Pavers

Shape Type B

Dentated units which key into each other on two sides, are not (usually) laid in herringbone bond, and by their plan geometry, when keyed together, resist the spread of joints parallel to the longitudinal axes of the units and rely on their dimensional accuracy and accuracy of laying to interlock on the other faces.

Shape Type C

Units which do not key together and which rely on their dimensional accuracy and accuracy of laying to develop interlock.

TYPE A

TYPE B

TYPE C

Figure C254.1

C254-2 AUS-SPEC-1\QLD-C254 Mar 2000

3. Clay pavers are manufactured from clay, shale or argillaceous materials which may be mixed with additives. Clay pavers may have square, bevelled (chamfered), rounded or rumbled edges. They are generally rectangular in shape, with the length twice the width, plus 2mm.

Clay Pavers

4. Clay pavers are classified as either Class 1, 2, 3 or 4 according to their intended application, with increasing performance requirements (and thickness) from Class 1 to Class 4.

Classification

5. Laying patterns of pavers are identified as being either Herringbone, Basket- weave, or Stretcher as shown in Annexure C254-A. Each of these may be laid at either 90^o or 45^o to the line of edge restraints. A variation of Stretcher is the Zig Zag Running Bond, also shown in Annexure C254-A.

Pattern

C254.03 CHOICE OF PAVER TYPE, SHAPE, CLASS AND LAYING PATTERN 1. The choice of concrete or clay segmental pavers, the paver class (for clay pavers), shape type (for concrete pavers), shape name, colour, thickness and laying pattern shall be as shown on the Drawings for each area of application.

Type

2. Unless otherwise specified, concrete pavers for road pavements shall be placed in herringbone laying pattern and shall be in accordance with the requirements for the appropriate road application shown in Table C254.1.

Concrete

3. Unless otherwise specified, clay pavers for road pavements shall be Class 4,

minimum 65mm nominal thickness, and placed in a herringbone laying pattern. Clay

C254.05 GENERAL

1. The Contractor shall submit details of all proposed segmental paving materials, including bedding sand and joint filling sand. These details shall be submitted to the Superintendent for approval supported with test results from a nominated NATA registered laboratory, confirming that the constituents comply with the requirements of this Specification.

Penetrations

5. Where pavers are placed over an isolation, contraction or expansion joint in an underlying concrete pavement, a joint is to be provided in the pavers. The joint shall consist of 10mm thick preformed jointing material of bituminous fibreboard.

Formed Joints

6. Any foot or barrow traffic shall use boards overlaying paving to prevent disturbance of units prior to compaction. No other construction traffic shall be allowed on the pavement prior to compaction and provision of joint filling sand.

Construction Traffic

7. On completion of subsequent bedding compaction and joint filling operations, all

joints shall have widths within the range 2-4mm. Tolerance

C254.17 BEDDING COMPACTION

1. After laying the pavers the sand bedding shall be fully compacted and the surface brought to design levels and surface profiles by not less than two passes of a high frequency low amplitude plate compactor which covers at least 12 units.

Compaction shall continue until all pavers form a smooth surface with adjacent paver edges matching. The level difference between adjoining edges of any two pavers shall be a maximum of 2mm, to avoid trip hazards, unless approved otherwise by the

Compaction

(14)

Superintendent for rough textured pavers.

2. Any units which are structurally damaged during bedding compaction shall be removed and replaced. The pavement shall then be recompacted for at least one metre surrounding each replacement unit.

Damage

3. The paving operations shall be arranged so that the use of the plate compactor proceeds progressively behind the laying face without undue delay, and such that compaction is completed prior to cessation of construction activity on any day.

Compaction shall not be attempted within one metre of the laying face except on completion of the pavement against an edge restraint.

Progressive Compaction

4. The finished surface level shall not vary from the design level at any point laid in any direction, by more than 6mm for all areas with Class 4 segmental pavements and 8mm for all other areas of segmental paving. Notwithstanding this, the finished surface of the segmental paving, including where the paving abuts an edge restraint other than a drainage inlet, shall not deviate from the bottom of a 3m straight edge laid in any direction, except at grade changes, by more than 6mm for road pavements and 8mm for all other areas of segmental paving.

Finished Levels

5. The channels formed between abutting chamfered units shall finish with their

inverts not less than 5mm nor more than 10mm above adjacent drainage inlets. Drainage Inlets 6. All compaction shall be complete and the pavement shall be brought to design

profiles before spreading or placing sand filling in the joints. Joint Filling

C254.18 FILLING JOINTS

1. As soon as practicable after bedding compaction, and in any case prior to termination of work on any day, dry sand for joint filling shall be spread over the pavement and the joints filled by brooming.

Timing

2. To ensure complete filling of the joints, both the filling sand and pavers shall be

as dry as practicable when sand is spread and broomed into the joints. Condition 3. The pavement shall then receive one or more passes of a plate compactor and

the joints then refilled with sand, with the process then repeated sufficiently to ensure that the joints are completely filled.

Process

C254.19 PROTECTION OF WORK

1. Other than wheeled trolleys, forklifts and cluster-clamp vehicles, construction and other traffic shall not use the pavement until bedding compaction and joint filling operations have been completed.

Restricted Use

C254.20 OPENING TO TRAFFIC

1. As soon as practicable after the filling of joints, construction vehicles may use the pavement, and should be encouraged to traverse the greatest possible area of pavement to assist in the development of 'lock-up'.

No Tracking

2. Excess joint filling sand shall be removed prior to opening to traffic. Excess Sand 3. The pavement shall then be inspected by the Contractor at regular intervals up

until the expiration of the Defects Liability Period to ensure that all joints remain completely filled.
